I hate burst anyone's bubble -- but all of the DO schools emphasize the various aspects of 'DO-ness'...now, each school may place more or less value on specific characteristics of 'DO-ness'. The trick to being the most content with the medical school you choose to attend, be it DO or MD, is to find one that fits your personality. Therein lies the rub!
(Would you buy an poorly fitting interview suit and hope to grow into it? Hell no, you select one of the bat that fits well or have IT tailored to fit YOU!)
Furthermore, and all the OMM/DO-hardcore-church members may attempt to rain down hell-fire and damnation on me for saying this...the way you interact with & treat (holistic medicine)patients & your 'style' of doctoring is much much more a function of "you" the person who dwells within your skin. Your patient - physician relations will be highly influenced by and largely an extension of your own interpersonal relationship skills and tendancies & these are things that can not be taught in a classroom; but must be learned by experiencing life.
In 15+ years of working w/i the allied health professions prior to medical school, I have encountered highly "osteopathic" MDs & DOs and some major MD & DO @$$holes. Believe me, the school or medical education paradigm had little to do with how "ostepathic" they were.
My word of advice to all of you struggling with this rhetorical question: find something more noteworthy and substantiable to expend your excess energies upon. There are many community clinics out there who could use your extra time, effort & talents helping the underprivileged...go volunteer.
Once you're out in the clinical real-world, your physician peers, allied health professions colleagues and, most importantly, your patients could give a rat's @$$ about the alphabet soup behind your sig. More than likely, with the classic doc's sig, they won't be able to read it anyhow. You will have to earn your stripes and their respect thru performance, empathy and compassion -- those are far more strenuous and applicable markers of success as a physician than some silly-@$$ed initials behind your signature!
My humble opinion...
